Title
(EN) PNEUMATIC TIRE FOR TWO-WHEELED VEHICLES
(FR) PNEUMATIQUE POUR VÉHICULES DEUX-ROUES
(JA) 自動二輪車用空気入りタイヤ
Abstract
(EN)
A pneumatic tire for two-wheeled vehicles, comprising a belt on a tire tread, said belt including: a peripheral direction belt layer having a plurality of cords extending in the tread peripheral direction that are covered by rubber; and a width direction belt layer provided on the outer side in the tire radial direction of the peripheral direction belt layer, and having a plurality of cords extending in the tire width direction that are covered in rubber. The pneumatic tire for two-wheeled vehicles is characterized by: having cushion rubber sections arranged on the outer side in the tire radial direction, and separated in the tire width direction across the tire equatorial plane; having base rubber having a higher elasticity modulus than the cushion rubber, arranged in a separated area or on the outer side in the tire radial direction; the length (Wn) of a separated area in the tire width direction cross-section and the length (Wb) of the base rubber in the tire width direction cross-section fulfilling the relationship Wn>Wb.

L'invention concerne un pneumatique pour des véhicules deux-roues, comprenant une ceinture sur une bande de roulement du pneumatique, ladite ceinture comportant : une couche de ceinture de direction périphérique ayant une pluralité de nappes tramées s'étendant dans la direction périphérique de la bande de roulement, lesquelles sont recouvertes de caoutchouc ; et une couche de ceinture dans la direction de la largeur, prévue sur le côté extérieur dans la direction radiale du pneu de la couche de ceinture dans la direction périphérique, et ayant une pluralité de nappes tramées s'étendant dans la direction de la largeur du pneu, lesquelles sont recouvertes de caoutchouc. Le pneumatique pour véhicules deux-roues est caractérisé par les caractéristiques suivantes : il présente des sections de caoutchouc d'amortissement disposées sur le côté extérieur dans la direction radiale du pneu et séparées dans la direction de la largeur du pneu en travers du plan équatorial du pneu ; il présente une base en caoutchouc ayant un plus grand module d'élasticité que les sections de caoutchouc d'amortissement, agencée dans une zone séparée ou sur le côté extérieur dans la direction radiale du pneu ; la longueur (Wn) d'une zone séparée en section transversale dans la direction de la largeur du pneu et la longueur (Wb) de la base en caoutchouc en section transversale dans la direction de la largeur du pneu satisfaisant à la relation Wn>Wb.
